Work
A production ERP shipped as founding engineer, AI workflows with human-in-the-loop safety, realtime collaboration, Go systems built around durability, CDC and crash recovery, and correctness-sensitive C++ market infrastructure.
Founding Engineer · Production ERP
Production accounting & ERP platform built end-to-end as first engineer: a double-entry accounting core in PostgreSQL, filing-ready GST compliance, WhatsApp automation, and an AI document-import pipeline — replacing Tally workflows for real businesses.

Product & AI · AI document review & compliance workflow
Extracts invoices, POs and receipts with per-field confidence and char-accurate provenance, evaluates them against versioned compliance rules, and routes to humans only when policy says so.
Next.js / Fastify / PostgreSQL / Backblaze B2 / Gemini
Product & AI · Supervised AI support operations
Traced agent pipeline: injection scan, intent classification, grounded cited drafts — and financial write actions queued behind an explicit human approval gate. Not a chatbot; a supervised ops system.
Next.js / PostgreSQL / pgvector / Gemini
Product & AI · Realtime collaborative workspace
A lightweight Linear × Notion: Kanban collaboration over Socket.IO with presence, optimistic mutations with idempotency keys, and reconnect replay from a per-workspace event log.
Next.js / Socket.IO / MongoDB / React Query
Systems & Infrastructure · Durable workflow engine in Go
PostgreSQL-backed durable workflow engine with lease/fencing semantics and idempotent starts. Failure scenes SIGKILL workers mid-execution and prove stale completions are rejected (409) through the API.
Go / PostgreSQL / testcontainers / Next.js
Systems & Infrastructure · PostgreSQL CDC platform in Go
Change-data-capture from the Postgres WAL: pgoutput decoding with TOAST awareness, idempotent replay per source transaction, and fenced LSN checkpoints proven by crash-replay testcontainers suites.
Go / pgoutput / gRPC / HMAC webhooks / Next.js
Systems & Infrastructure · Durable execution for MCP tool calls
MCP server where every tool call is persisted before dispatch, executed under fencing-token leases, and inspectable from Postgres. The hosted demo kills its own executor to generate genuine crash-recovery events.
Go / MCP / PostgreSQL / Next.js
Trading & Performance Systems · Real-time market data & execution simulation
C++20 engine that reconstructs L2 order books from live exchange snapshot/delta streams, simulates execution against observed depth, and enforces deterministic live/replay parity.
C++20 / WebSocket / CMake / ASan+UBSan / TSan / Next.js
Additional Engineering Work · Accessible React component system
15 keyboard-first components with hand-rolled ARIA patterns, controlled/uncontrolled APIs, and design-token theming without a headless-UI dependency.
React / TypeScript / ARIA / Design tokens
Additional Engineering Work · Node-based workflow builder
Normalized graph state with structural sharing, coalesced undo/redo, cycle-safe connect-time validation, deterministic canonical-JSON serialization, and an inspectable execution simulator.
React Flow / Zustand / TypeScript
